Research on Construction Technology of Slurry-supported Rotary Drilling Hole Filling Cast-in-place Pile in Bridge Pile Foundation Engineering—Taking Cangrong Xunjiang Bridge in Wuzhou City,Guangxi Province as an Example
Taking Cangrong Xunjiang Bridge in Wuzhou City,Guangxi Province as an example,this paper conducts in-depth research on the construction technology of slurry-supported rotary drilling hole filling cast-in-place pile in bridge pile foundation engineering.Firstly,the rotary drilling hole filling process of slurry-supported cast-in-place pile is studied,and the process of rotary drilling hole filling is designed in detail.Secondly,the preparation and pouring of underwater concrete are carried out to ensure that the quality of pile foundation engineering meets the requirements,and then the design of construction technology of slurry-supported rotary drilling hole filling cast-in-place pile in bridge pile foundation engineering is completed.Finally,the results of the case analysis show that with the increase of the hole depth,the inclination of the hole center position increases,but the test results of the engineering meet the construction requirements,which proves that the technology has high feasibility.
